Definitions
- This invention relates generally to high density pad-to-pad connectors utilizing flexible circuit for forming connections, and more particularly to a method and structure for forming precisely aligned connections in a pad-to-pad configuration with flexible circuit technology.
- the card is slid into the slot, and at the end of the slot, the connector pads on the mother board are connected by flexible circuit technology to connector pads on the daughter card.
- the connection would, to a great extent, be self-aligning in that the pins would physically plug into the holes.
- pad-to-pad connection i.e., connecting pads on flexible circuit in compressive engagement with pads formed on the mother board, there is no such "self-aligning" feature available.
- an electrical connector assembly and method for connecting at least one end of a flexible circuit to a substrate with the contact pads of each in precise alignment has at least one floating frame member which has first and second exposed surfaces. At least one fine or precise alignment pin extends from the first surface and is configured to mate with an alignment opening in the flexible circuit.
- a support member is provided which has a support surface which slidingly engages the second surface of the floating frame member to permit sliding movement thereon by the sliding frame member.
- a registration or coarse alignment pin is provided which is operatively associated with the floating frame member and the support member and configured to engage the substrate to roughly align but allow relative sliding movement of the floating frame member with respect to the substrate when the registration pin engages the substrate.
- the overall concept of the present invention is to provide a self-aligning feature for pad-to-pad connection of flexible circuit which is used in forming connections between connector pads on different substrates.
- Such connection includes connection between electrical pads on a circuit board and electrical pads on cards being connected thereto, or connections between the circuitry on opposite sides of circuit cards which are to be utilized in a stacked configuration.
- the present invention provides for a self-aligning feature during connection or assembly to assure that there is proper precise alignment between the pads on the flexible circuit and the pads on the substrate being connected.
- a connector 20 formed according to the present invention is shown.
- the connector of this embodiment is especially useful and adapted to connect a card, such as a PC I/O card to a substrate, such as the planar board of a personal computer, wherein the card extends perpendicularly to the planar board.
- the connector 20 includes a generally rectilinear housing 22 which has a flexible circuit support surface 24 formed as one face thereof. An elastomeric pad 26 is bonded to the support surface 24.
- the housing 22 also includes a frame support surface 28 which is the face adjacent to and extending generally perpendicular with respect to the flexible circuit support surface 24.
- a pair of threaded openings 32 extend through the housing 22 and intersect the frame support surface 28.
- a pair of flexible circuit alignment pins 34 extend from opposite sides of the support surface 24 and a pair of pin-receiving slots 36 extend inwardly from the support surface 24. These are positioned to receive mating pins 34 from an adjacent connector 20 during assembly of the cards as will be described presently.
- the housing 22 also has threaded screw receiving openings 38 extending therethrough from the support surface 24.
- a sliding or alignment frame 40 is provided which has a flexible circuit supporting surface 42 formed on one side thereof. Fine adjustment pins 44 extend upwardly on opposite sides of the flexible support surface 42. An elastomeric pad 46 similar to the elastomeric pad 26 is bonded to the flexible surface support surface 42.
- the sliding frame 40 is provided with a pair of registration apertures 48 which extend therethrough and are positioned to be aligned with the threaded openings 32 of the housing 22.
- a flexible circuit (sometimes referred to as flex circuit) member 50 is provided which has a first set of pads 52 and a second set of pads 54. The first and second sets of pads are connected by circuitry 55 in the form of conducting wires or traces.
- a first pair of alignment openings 56 are provided in the flexible circuit 50, which alignment openings are in a predetermined, precise alignment with respect to the first set of pads 52, and a second pair of alignment openings 58 are approved which are located in a precise alignment position with respect to the second set of pads 54.
- a pair of screw-receiving openings 60 is provided at opposite ends of the flexible circuit 50 adjacent to pads 52 in alignment with the threaded screw-receiving openings 38 on the flexible circuit 50.
- a pair of pin-receiving openings 61 is provided adjacent the openings 60 and positioned to receive pins 34 from a mating connector when the connectors are joined to engage a board as will be described presently.
- a pair of joining screws 62 are provided which serve to join two opposite connectors 20 engaging a card to form a card assembly as will be described presently.
- a pair of threaded coarse alignment bolts 64 are provided which are adapted to threadably engage the threaded openings 32 in the housing 22 to mount and coarsely or roughly align the connector 20 when it is attached to a board as will be described presently.
- the coarse alignment bolts 64 have pointed tips 66, the purpose of which will be described presently.
- a group of four connectors (three of which are shown) are used to connect the connectors 20 to a daughter card designated generally as 70 to form a card assembly.
- the daughter card 70 has circuitry 72 on both sides thereof, the circuitry being provided with the necessary input pads 74 formed thereon. These pads 74 are positioned to align with pads 52 on flex circuit 50 of one of a respective connector 20 when the connector 20 is attached to the card 70.
- the connectors are assembled such that there are two connectors 20 on each side of the card, each of the two connectors having an opposed connector 20 on the opposite side of the card.
- Each connector is first assembled as shown in Figure 3, with the sliding frame 40 engaging the frame support surface 28 and freely movable thereon within the constraints of the pins 64.
- the flex circuit 50 for each connector is precisely registered with respect to the pads 54 thereon by pins 44 on the frame member 40 and the pads 52 precisely aligned by means of pins 34 on the surface 24 of the housing 22.
- the pair of screws 62 extend through these openings 38, as well as through the openings 60 in the flexible circuit 50, and when drawn up tight cause compressive engagement of the pads 52 against the pads 74 on opposite sides of the card 70, thus assuring good contact.
- the elastomeric pad 26 assures good, uniform force. Precise alignment is obtained by means of the alignment pins 34 passing through openings in the card (not shown) and into the slots 36 on the connector on the opposite side of the card. This will precisely align the two connectors on opposite sides of the cards to each other and to the board. This is normally done as a factory operation, and hence the alignment can be readily achieved by an assembly. It is in the condition shown in Figure 4 that the card assembly is in position to be connected to a circuit board 80.
- the circuit board 80 includes a first set of pads 82 and a second set of pads 84, the pads 82 being positioned to engage the pads 54 on the two connectors on one side of the card, and the pads 84 being positioned to connect to the pads 54 on the connectors on the opposite side of the card 20. Further, it is to be understood that the board 80 in this environment is typically located at the end of a slot in a personal computer, and thus the card 70 with the connectors attached thereto must be slid into the slot and then secured to the board 80.
- the board 80 typically will have a stiffener 86 with threaded holes 88 therein, with the threaded holes being in alignment with mating threaded holes 90 formed in the board 80.
- the card 70 with the connector 20 oriented inwardly is slid into the slot or opening in the frame of the personal computer, and the threaded coarse alignment bolts 64 engage the holes 90 and holes 88 to cause the connection.
- the eight coarse alignment bolts 64 are then screwed down tight to cause engagement of the pads 54 on the various connectors 20 to engage the pads 82 and 84 on the board 80.
- the self-aligning feature is shown somewhat diagrammatically in Figures 5-7 as the bolts 64 are tightened. As can be seen, the bolts are shown coming up from the bottom of the board 80, but it is immaterial whether they come from the top or the bottom, the determining factor being where the pads 82 and 84 are located. As shown in Figure 5, the card 70 with the attached connectors 20 are pushed into whatever slot on the computer accommodates the card until the pointed ends 66 of the bolts 64 just engage the registration holes 90 in the board. As can be seen in Figure 5, the alignment of the bolts 64 can be off significantly from the holes 90. This much misalignment, which can be ⁇ as mush as ⁇ 2.5 mm, cannot be tolerated.
- the pointed tips 66 of the bolts 64 are pushed by action of the surfaces of the holes 90, causing the entire assembly of card 70 and connectors 20 to move until the bolts 64 are in alignment with the holes 90, as the torquing or screwing of the bolts 64 draws the card 70 and associated connectors 20 toward the board 80, the bolts 64 and holes 90 providing a rough alignment of the pads 54 on each of the connectors 20 with the corresponding pads 82 and 84 on the board 80 as shown in Figure 6.
- the frame 40 has limited sliding movement available responsive to the interaction of the pins 44 and the alignment openings 42.
- the sliding frame 40 will move the flexible circuit into a position where the pads 54 align precisely with the respective pads 82 or 84 on the board 80.
- This final position is shown in Figure 7, with the contacts 52 on each flexible circuit 50 being precisely aligned and compressively engaged (due to the elastomeric pad 46) with the respective pads 82, 84 on board 80.
- each connector 20 i.e., the sliding frames 40 on each of the connectors can move independently of the movement of the sliding frames 40 on any other connector, thus allowing each connector to precisely align its respective flexible circuit 50 with the pads 54 thereon with the mating pads 82 and 84 on the board 80.
- the elastomeric pad 46 provides the necessary resilient force to ensure a good connection.
- a connector using a short run of flex cable can be used to make pad-to-pad surface connections for mounting a card to a board, and this connection is possible even when the card is inserted in the slot for blind connection. Because of the construction, this invention allows for both coarse and fine registration or alignment of the pads with respect to each other.
- a guide is provided for a tool to allow tightening of the card onto the board and also a modified structure for mounting the card onto the board is provided.
- all the elements of the connector 20 as previously described are the same, with the exception that the coarse alignment bolts 64 of the previous embodiment are replaced with unthreaded or smooth coarse alignment bolts 64a, and the openings 90 and 88 of the previous embodiment which were threaded are replaced with openings 90a and 88a which are smooth and unthreaded.
- the card 70 has disposed on one surface thereof a stiffener bar 93 and elastomeric pads 94.
- the card 70 is designed to be inserted into a cage, not shown.
- a pair of tool guides 98 are provided one on each side of the card 70, each of which has a plurality of "C" shaped sections 100 and terminates in a guide plate 102.
- the guide plates 102 each have a slot 104, which slot is configured to removably receive a clamp 106.
- Each clamp 106 has a central opening 107 through which a threaded actuation bolt 108 extends and a card engaging slot 109.
- the board 80 to which the card is being connected contains a pair of threaded openings 110, and the stiffener 86 contains threaded opening 111 positioned to receive the actuation bolt 108, as shown in Figure 9.
- the tool guides 98 engage the edges 112 of the card 70 with the connectors 20 secured thereon with its edges positioned in slots 109 of clamp 106 as shown in Figure 9.
- This assembly is then inserted into a cage (not shown) and the actuation bolts 108 are aligned with the threaded openings 110 in the board 80.
- the tightening tool which can be a long handle wrench or a screwdriver depending upon the head configuration of the actuation bolt 108, is inserted using the sections 100 as a guide, and the actuation bolts 108 are tightened.
- the unthreaded coarse alignment bolts 64 engage the smooth registration holes 90a and smooth openings 88a to provide the coarse alignment as in the previous embodiment.
- the slots 109 in clamp 106 are larger than the thickness of the card 70 and thus limited movement of the card assembly of the card 70 and connector 20 is permitted until the bolts 108 receive the connector 20 firmly to the card.
- the actuation bolts 108 are tightened down on both sides, the fine alignment pins 44 coact with the openings 92 to provide the fine alignment just as previously described.
- the section guide may be left in place or, if desired, a notch 113 can be provided in the tool guide 98 between a pair of sections 100. The sections can be broken off after use so that they do not extend past the end of the slot.
- FIG. 10-12 Another embodiment of the connector using flexible circuit according to this invention is shown in Figures 10-12.
- This embodiment is adopted to connect two or more cards in a physically parallel stacked configuration by using connectors to connect the circuitry on the back side of one card to the circuitry on the front side or facing side of an adjacent card, using flexible circuit and pad-to-pad contact.
- no separate housing member is utilized, but rather a pair of frame members 40 provides the support for each segment of flexible circuit 50.

- the connecting pads 52 and 54 are in opposed relationship, i.e., disposed on opposing surfaces and oriented 180° away from each other.
- a series of cards 70a is provided, each of which has openings 71a therein.
- the cards 70a are aligned as shown in Figure 12, and the connectors formed of the sliding frames 40 are interposed between each pair of cards as shown therein.
- Screws 120 pass through the opening 71a in the boards and engage a stiffener 122.

- the cable 50 is provided with a cable stiffener 152, which has a pair of openings 154 therein which align with openings (not shown) in the cable 50.
- a pair of screws 160 are provided which secure the cable 50 and the cable stiffener 152 to the frame member 132 by passing through the openings 154 and openings in the cable and then threadably engaging the threaded openings 136 and the housing 132.
- the cable 160 is engaged by the sliding frame 40 in a manner similar to that described in previous embodiments, with the fine alignment pins 44 passing through the openings 148 in the flexible cable 50.
- the cable is connected to a board as shown in Figure 2A or card 170 as shown in broken outline in Figure 14.
